Abstract

The utility model relates to a vehicular air-conditioning condenser which belongs to the field of the automobile parts. The structure of a current-collecting pipe is a parallel-flow type condenser is changed so as to increases the heat exchange area of the parallel flow type condenser, the circular pipe type structure of the current-collecting pipe (1) is changed into a bow structure with semicircular radial cross section, both ends of a multihole flat pipe (2) are welded on circulating holes (4) on an axial plane on which a bow straight line is positioned, the circulating holes (4) are distributed parallelly and axially along the radial direction in a single row, double rows, three rows or four rows, and the porous flat pipe (2) corresponds to the circulating holes (4). The utility model has the advantages that the effective length of the porous flat pipe (2) and the thickness of the condenser can be increased by the current-collecting pipe (1) under the conditions of identical height and equivalent material consumption, so that the heat exchange area of the parallel-flow type condenser is increased, the refrigerating capacity is increased, the operational requirements for vehicles larger than medium size buses can be met and simultaneously no additional investment is basically increased for manufacturing technology and equipment.

Description

A kind of automotive air-conditioning condenser

Technical field

The utility model belongs to the auto parts and components field, relates to a kind of automotive air-conditioning condenser.

Background technology

In the prior art, condenser is the core component of air conditioning for automobiles, and minibus and motor bus mostly adopt corrugated tube type or tube-fin condenser, promptly pipe left and right snakelike curved around condenser, its heat exchange area is big, but efficient is low, it is big to take up room, consumptive material is many; Car adopts advanced parallel flow type condenser basically, be that the be parallel to each other two ends of formula of many porous flat pipes are welded on respectively on the header of two circles, according to the partition in the header, change the flow process of cold-producing medium, can make full use of effective heat exchange area well, but circular header has significant limitation for the heat exchange area that increases porous flat pipe, generally can only directly upwards weld a general porous flat pipe at it, be difficult to increase effective heat exchange area, and the condenser of most of cars is at height, space on the width is fixed, and bigger adjusting space is arranged on thickness (being the radial direction of header), circular header has then limited the utilization to this adjustable space, the aspect is owing to have the general of less types of porous flat pipe now in addition, therefore, the parallel flow type condenser of existing structure can not satisfy the requirement of the above vehicle of mini-bus.

Summary of the invention

The technical problem that solves:

Change the structure of tubular type header in the parallel flow type condenser, adopting radial section is the arched header of semicircle shape, overcome the deficiencies in the prior art, make header under the condition of equal height, consumption equivalent material, can increase the effective length (being the width of condenser) of porous flat pipe and the thickness of condenser, thereby increase the heat exchange area of parallel flow type condenser, improve refrigerating capacity, make its instructions for use that can satisfy the above vehicle of mini-bus, on manufacture technology and equipment, need not to increase investment simultaneously basically.

The technical scheme that adopts:

A kind of automotive air-conditioning condenser, has header 1, the import and export 6 and 7 of cold-producing medium is housed on it, partition 5 also is housed in the header 1 regularly, be contained in two porous flat pipes 2 between the header 1 in addition, be contained in the wave heat-radiation belt 3 and the support 9 of the window that blows between the porous flat pipe 2 in addition, it is characterized in that: the radial section of header 1 is the arc of semicircle shape, and the two ends of porous flat pipe 2 all are welded on the opening 4 on the axial plane of header 1 at arc straight line place.

Beneficial effect:

Employing has the arched header 1 that radial section is a semicircle shape, can make header 1 under the condition of equal height, consumption equivalent material, increase the effective length of porous flat pipe 2 and the thickness of condenser, thereby increase the heat exchange area of parallel flow type condenser, improve refrigerating capacity, make its instructions for use that can satisfy the above vehicle of mini-bus, on manufacture technology and equipment, need not to increase investment simultaneously substantially.

The specific embodiment

Further explanation in detail in conjunction with the accompanying drawings;

Shown in Fig. 1～4, opening 4 on the axial plane of the header 1 at the arc straight line place of the bow-shaped cross-section of the radially semicircle shape of header 1, its along header 1 radially and be single-row, biserial, three row or four column distributions of the axial side-by-side of header 1, porous flat pipe 2 is welded on the opening 4 with same distributed architecture; The width m of opening 4 equates, and corresponding with the thickness of porous flat pipe 2; The length L of opening 4 is corresponding with the width of porous flat pipe 2 and wave heat-radiation belt 3, and the length L of opening 4 equates in same row, in different lines or equate, or unequal; Spacing n between the adjacent two current drainage through holes 4 equates, and corresponding with the thickness of wave heat-radiation belt 3.

Shown in Fig. 2,3, the two-end part of header 1 is circular, and has the closure plate 9 of sealing.

As shown in Figure 4, also have partition hole 8 on the header 4, partition 5 inserts in the partition holes 8 and welds together with the inner wall sealing formula of header 1; Partition 5 is different with fluid volume according to the shared volume of gas of the cold-producing medium of of the same race, homogenous quantities, and data relevant with reflux process length and being provided with.

The multiple layer of header 1 usefulness aluminium sheet material is manufactured and is formed, and multiple layer aluminium sheet is meant to have the thin aluminum sheet that can supply the composite layer of soldering on the surface, and this composite layer can melt under 570～595 ℃ temperature automatically, thereby finishes soldering; Porous flat pipe 2, wave heat-radiation belt 3, partition 5 etc. are all planted material thus and are manufactured and form.Header 1 together with 8 processing of opening 4 and partition hole manufacture finish after, again with the import and export 6 of porous flat pipe 2, wave heat-radiation belt 3, partition 5, closure plate 9 and cold-producing medium and 7 and header 1 common assembly be one, form through a soldering of hot melting furnace.
